function [b,idx] = sortrows(a,vars,sortMode) %SORTROWS Sort rows of a timetable. % B = SORTROWS(A) returns a copy of the timetable A, with the rows sorted % in ascending order by time. % % B = SORTROWS(A,VARS) sorts the rows in A by the variables specified by VARS. % VARS is a positive integer, a vector of positive integers, a variable name, % a cell array containing one or more variable names, or a logical vector. The % rows in B are sorted first by the first variable, next by the second % variable, and so on. Each variable in A must be a valid input to SORT, or, % if the variable has multiple columns, to the MATLAB SORTROWS function or to % its own SORTROWS method. % % VARS may also contain a mix of positive and negative integers. If an % element of VARS is positive, the corresponding variable in A will be sorted % in ascending order; if an element of VARS is negative, the corresponding % variable in A will be sorted in descending order. These signs are ignored % if you provide the MODE input described below. % % B = SORTROWS(A,'Time') sorts the rows in A by time, the default behavior. % % B = SORTROWS(A,VARS,MODE) sorts A in the direction(s) specified by MODE. % When MODE is 'ascend' (the default) or 'descend', SORTROWS sorts A in % ascending or descending order, respectively, for all variables specified % by VARS. MODE may also be a cell array containing the character % vectors 'ascend' or 'descend' to specify a different direction for each % variable specified by VARS. Specify VARS as 1:SIZE(A,2) to sort using % all variables. % % [B,IDX] = SORTROWS(A, ...) also returns an index vector IDX such that % B = A(IDX,:). % % See also ISSORTED, UNIQUE. % Copyright 2016 The MathWorks, Inc. if nargin < 2 vars = a.metaDim.labels(1); end if nargin < 3 [b,idx] = sortrows@tabular(a,vars); else [b,idx] = sortrows@tabular(a,vars,sortMode); end
